Abstract: 1382397 Hydrocracking catalysts UNION CARBIDE CORP 15 Feb 1973 [16 Feb 1972] 7413/73 Heading B1E A process for preparing a catalyst comprises providing a zeolite Y molecular sieve having a SiO 2 /Al 2 O 3  molar ratio of at least 4.0, an alkali metal cation content of from 10 to 30 equivalent percent and complementarily from 90 to 70 equivalent percent non-metallic cations; heating said molecular sieve at a temperature of from 350C to below the crystalline destruction temperature for a period of at least 0.1 hr., said heating within the said temperature range being the first such heating to which the molecular sieve in its present cation form has been subjected; cooling the decationized molecular sieve to less than 300C and contacting same with an aqueous ammonium ion solution to reduce the alkali metal cation content by ion exchange to less than 10 equivalent percent alkali metal cations, the pH of the said ammonium ion solution in contact with said molecular sieve being in the range of 4 to 8; thereafter forming a composition by intimately admixing the resulting molecular sieve product with finely divided alumina, an alkali metal-free water soluble salt of at least one non-noble metal of Group VIII of the Periodic System, at least one water soluble alkali metal-free compound of a metal of Group VI-B of the Periodic System and water, said Group VI-B metal being present in an amount of from 10 to 30 weight percent calculated as the metal oxide based on the total weight of Al 2 O 3  plus zeolite present (solids basis), said Group VIII metal being present in an amount of from 2 to 10 weight percent calculated as the metal oxide based on the total weight of Al 2 O plus zeolite present (solids basis), and said water being present in an amount sufficient to render said composition a thixotropic extrudable mass; and extruding the composition thus formed and at least partially dehydrating the extrudate. The Group VI metal may be Cr, Mo or W, the Group VIII metal may be Co or Ni. In Examples catalysts are made from alumina, ammonium zeolite Y, ammonium paramolybdate, and nickel nitrate mixed with nitric and phosphoric acids, extruded, dried and calcined at 550C, and from ammonium zeolite Y, nickel nitrate, nickel carbonate, ammonium paramolybdate and alumina mixed with nitric acid, extruded, dried and calcined at 500C.

Abstract: 1303532 Measuring toe-in of vehicle wheels FMC CORP 16 Feb 1970 [17 Feb 1969] 7425/70 Heading G1X [Also in Division G2] A method for measuring the toe-in of a pair of vehicle steerable wheels 10, 11 comprises mounting a projector 30 Fig.1 on each of the front wheels of a vehicle, projecting an image of a reference mark 33 forwardly towards a mirror 23 mounted in a background unit 12, reflecting said image back towards the projector 30 and re-reflecting the image from mirror 36 on to a horizontal scale 22, so magnifying the extent of toe-in on to an enlarged scale. The background unit Fig.4 comprises a frame 16 supporting a front panel 17 through which light may be reflected on to a plane mirror 23, movable perpendicular to a reference plane 13, and by reflection from mirror 36 on to scale 22 disposed in the back of shadow box 18, which is movable parallel with the plane 13 by the use of tabs 20. In operation, the projectors are first aligned with target scales (40) Fig.2 (not shown) on the rear wheels such that each wheel gives an identical reading on the scales. The projectors are then aimed at the background unit 12 and mirror 23 is adjusted until equal readings are given on scales marked on the projector mirrors 36 so that the mirror bar 24 is thus positioned parallel with reference line 14. The wheels are then turned in an arc until the image from the right hand projector is reflected to the zero point of the projector mirror 36 and scale 22 is adjusted until the reflected image also falls on its zero point. The wheels are then further turned such that the image from wheel 10 falls on the zero point of its projector mirror and having thus ensured that wheel 10 is normal to the plane 14, the total toe-in five times the original scale size may be read from the image, projected from wheel 11, on the right hand scale 22.

In a further embodiment, Fig. 4 (not shown) the air is delivered to the tuyeres formed in the forward edge of the plates (6) by pipes (29) extending from back to front of the plates. The pipes (29) are connected to the header pipes (10) by a transverse pipe (30). A still further embodiment, Fig. 5 (not shown) has plates (36) of heat resistant metal with air feed pipes (40) attached to the plates, and located under the plates.
